SPECIFICATION forming part of Letters Patent No. 626,314, dated June 61899.

Application filed .Tune 6, 1898. Serial No. 682,634. (No model.)

To @ZZ whom it may concern:

Be it known that we, FRIEDRICH Wnvnn and CARL SEEL, subjects of theEmperor of Germany, residing at Barmenin the Province of RhenishPrussia, Germany, have invented certain new and useful Improvements inLooms; and we do hereby declare the following to beafull, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to to the shape of the fabric to beproduced;

second, by the peculiar design of the reed, which also in each casevaries according to the shape of the breast-beam; third, by the specialmanner of arranging the mails in the heddles, which instead of lying ina straight line, as usual, are arranged in a line correspondingapproximately to the general outline of the breast-beam and of the loweredge of the reed; fourth, by the race-board of the shuttle and the meansfor producing a clean shed; fifth, by the peculiar means for working thereed, so that it can be driven close up upon the breast-beam and beat upa longer weft-thread than the apparent width of the woven stuff.

On the accompanying drawings the new loom is shown as a whole and invarious details and the manner of its working shall be explainedhereinafter.

Figure l shows avertical section along line I I of Fig. 2. Fig. 2isaplan of Fig. l. Fig. 3 is a front view seen from the left of Fig. l.Fig. 4c shows a part of the loom in vertical section, serving to explainthe working of the reed and of the shuttle-race. Fig. 5 shows in frontview part of the loom with the reed behind the shuttle-race and thecentral part of this in normal position. Fig. 6 shows one example ofarranging the mails in the heddies. Fig. 7 shows a detail view of thereed G, illustrated also in Figs. 3 and 5.

In a frame A is mounted the main shaft B, which is driven by fast andloose pulleys C, and from which the other movable parts 0f the loom areset in motion, as will be explained farther on. At the right or rearside 0f the frame is placed a light wooden frame E, containing thewarp-bobbins, in place of a single warp-beam, as usual, the nature ofthe fabrics intended to be produced by our new loom requiring differentlengths of warp at different places of the weaving, and thereforespecial means for giving off various lengths of yarn at differentplaces. From these bobbins the yarn is drawn in to the heddles F and thereed G, and thence around the breastbeam H. The heddling and reediu gare done as usual, with the difference only that the mails in theheddles are not arranged in a horizontal or straight line, (only formaking small articles, ribbons, and the like the mails in the heddlesmay be arranged in a horizontal line,) but in a line corresponding inshape to the shape of the breast-beam, as clearly shown in Fig. 6. Thereed also differs from an ordinary reed in this respect: its bottom stayg instead of being straight, as usual, has also the curved shape of theoutline of the breast-beam. The reed further differs from an ordinaryreed by the manner of its working and arrangement in the loom.

The reed instead of being arranged in a batten is here held between twoguide-blocks K, which slide on two guide-bars L, mounted obliquely inthe main frame. These guideblocks have brackets 7.2 surlnounting them,on which the reed is so held that when it is fully pushed backward itwill stand behind the shuttle-race board, and when it is fully drawnforward-that is, toward the breast-beamits bottom stay will standexactly, or nearly so,

in the middle over the breast-beam. The.

moving forward and backward of the reed may be done, as in the exampleshown, by means of cams M and levers N and O, as is clearly shown inFigs. l and 2.

The breast-beam II is exchangeable and varies in form. It receivesalways the shape which is prescribed by the shape of the fabric to beproduced. In the example shown on the drawings it has a wavy form,resembling IOO 4is arranged the shuttle race-board.

gether a channel of half-circular form.

two side parts PP are fixtures. The central part P can be raised andlowered. The lowering has for its object to allow the reed to passthrough on its way backward .before a.

new weft is laid in. VThe raising of the middle part P' of therace-board has for its object to raise all those warp-threads which donot form a clean shed, so that when the part P is raised it not onlyforms a continuous semicircular race, together with the two other parts,but that it also brings up the warpthreads -into place, so that they doform a clean surface for the shuttle to pass over in the Lrace-board.

lThe raising and lowering ot' the movable part P of the race-board isdone by means-of cams Q, levers R, and bars S, properly arranged in theloom between the two main frames, a spring T serving to pull the leversdownward and keep their rear ends in conf jtact with the cams.' 1 'Thedriving-gear forthe sh uttle-'the pickeri driver in ordinary looms-isarranged'as follows: At both sides ofthe main shaft bevel-i wheels U areplaced, gearing together with? similar wheels U on obliquely -arrangedshafts V, held in suitable brackets at the;

sidesvof the frames and atthe upper ends of',

pulled against them by springs Y, which are Txed with one end on themain frame and with the other upon arms Z, which are made' tooscillate-on a bolt a, upon which they are lkeyed andwhich is suitablycarried andh'eld i in the cross-beam Z) of the frame.

bolt a are also ixed the (picker) drivers c, which,with theircircularlyshaped ends,reach into lthe race-board of the fixed parts PP.It

will be observed that the bolt a lies in the,

center of the circle of the race-board.

Finally, we have to call attention to a small bar d, which'isplacedexactly over the breast-y that the-reedwhen beating fast aweft-thread 'and'being driven quite forward upon the cen- .terlinefof-the beam'does not'require to raise the threads; otherwise by itsmovement it might easily happen that thin threads are torn, which isprevented by passing the warp over the thin bar cl.

Variations :in minor details may be made;

butinjthemain the loom described and shown 1s new, and so isits working,of which we let which are keyed volute cams W. These vo lutevcam's workagainst `slides X, which are" On they It `has follow a shortdescription. This is as follows: The drawing andrheddling of the warpinto the reed and the heddles having been done as usual and the yarnhaving been drawn over the bar d and around the breast-beam, which isroughened byvany of the known means, the shed is opened and the reed ispushed backward into the position shown in Fig. l in full lines anddotted lines in Fig. 4.' The loose part P' of the shuttle race-board isthen raised and brought in position that-the race in the three parts P PP forms a continuous circular channel. The shuttle, with theweft-thread, is then driven through the shed by means of the drivers ccand their connections, and then the part P' is dropped again and thereed is pushed or pulled forward to beat the weft into l the warptightand close to the bar d, so that the weft-threads follow as closelyas possible v the outline of the breast-beam, and the now already wovenfabricthat is, the intermes'hed warp and weft threads-forms the exactwrapper of the breast-beam, so that when Ithis is being turned bytheordinary means-'that is, a regulator of any known kand suitabledesignthe woven stuff is pulled forward while the weaving is going on.It will, however,

i be observed that the pulling off of the woven stuff in our mode ofworking and with 'our peculiar `fabric cannot bedone, as usual, by theuse of a cloth-beam, upon whichthe stuff is wound, the peculiarity inthe 4shape of the goods produced not allowing this mode of working. Thestu if, or, as we might say, the partial wrapper of the breast-beam, istaken along with it by its rotation so much as to givesufiicient hold toit upon the breast-beam that it will be able to pull Aforward the warp.It then is taken off simply by carrying it over a barf and vis thentaken up by a suitable receptacle vplaced underneath the loom, or it maybe allowed to fall on the ground.

Thegist of the invention consists in this, that the loom is soconstructedand'so worked that, first, the reed is pulled `forward andbeats the weft-thread fast only Iright up in IIO the line of tangencebetween the warp-threads and the breast-beam, or-at any rate in aline asclose Itothat line of tangence that, practically speaking, the linegiven to lthe weftthread has the form of the outline of the breast-beamand that it cannot anymore alter this form or take another shape,as isthe case in ordinary weaving, where the weft is beaten tight at acertain distance from the beam, and that, secondly, the reed isenabledto distribute a greater length of weft-thread than corresponds to thereal length ofthe breast-beam. l'In order to be able to 'bring up thereed into the said position and beat the vweft tight upon thebreast-beam itself, it is necessary that the bottom stay of-the reedcorresponds in its vgeneral-form to the general outline of the breast-beam. Afurther condition is that means are provided to raise thewarp-threads of the lower shed so as to form a clean shed for theshuttle to pass through.

The mechanisms nsed for carrying out these ideas are of minorimportance, and they may vary in construction according to the generalarrangement of the loom.

Having noW particularly described and ascertained the nature of our saidinvention and in what manner the same is to be performed, We declarethat what We claim, and desire to secure by Letters Patent, is-

l. In a loom for Weaving shaped fabrics, the combination of abreast-beam conforming to the shape desired, with heddles having theirmails arranged in a line corresponding to the contour of the said beam,a reed having a bottom stay of shape also corresponding thereto, and thenecessary actuating and connecting` mechanism, substantially as setforth.

2. In a loom for Weaving shaped fabrics, the combination of abreast-beam conforming to the shape desired, with a bar d fixed closelyover the breast-beam near the line of tangency of the Warp-threadstherewith, heddles having their mails arranged in a line correspondingto the contour of the said beam, a reed having a bottom stay also ofcorresponding shape, and the necessary actuating and connectingmechanism, substantially as set forth.

3. In a loom for Weaving shaped fabrics, the combination with abreast-beam conforming to the desired shape, of heddles having theirmails arranged in a line corresponding to the contour of the said beam,a reed having a bottom stay of shape also corresponding thereto and thenecessary actuating and connecting mechanism, the length of the reed atthe top being equal to the total length of the Working part of thebreast-beam, its bottom being of equal length With the breastbeam andthe reed-bars converging from the said top toward the said bottomsubstantially as set forth. l

In testimony whereof We have affixed our signatures in presence of twoWitnesses.
